Specialty Uses of California Redwood 



Insulation — Ice Houses 

\ \;iv manufacturer of silos in the 
East, one of the pioneer concerns in 
the use <>i Redwood for sili makes 
tli' statement that 2 inches of Red- 
\\'".(| j^ equivalent to 30 inches of 
concrete in insulating power. This 
manu :turer has studied Redwood 
tt roughly from t i 1 i -» angle for the 
reason that the success of a silo de 
pends upon the non-conductivity of 



the silo wall — as dissipation of the 
natural heat of the -.ilage through 
the silo wall increases the per cent of 
waste silage. 

Redwood in growth structure is 
porous, and, when studied under a 
microscope, looks very similar to a 
comb of honey between the dark an- 
nular rings. Every one of these mil- 
lions of cells in the growing tree is 
full of sap, but when the tree is cut 
into lumber the lumber must be "sea-

snned" or dried, before it goes into 
commercial use. This "seasoning" 
process consists merely of evaporat- 
ing the natural moisture out of these 
cells. Each cell, therefore, becomes a 
dead air space. 

The cellular make-up of Redwood 
is uniform both in the thickness of 
the cell wall as well as the size of the 
cell. It is plainly evident, therefore, 
that heat applied to one side of a 
piece of Redwood, to travel through 
the Redwood must pass through a 
thin cell wall, then a dead air space, 
then another cell wall and then an- 
other dead air space, and so on. Heat 
passing through this combination 
rapidly dissipates. 

Prof. L. J. Towne, of Columbia 
University, gives the relative power 
of conduction as I to 20 between 
wood and stone, cement or cla} 
products. This means that stone and 
' • lent are 20 times a better medium 
fur the conduction of heat or cold 
than is wood. The millions of dead 
air cells between the annular rings 
f Redwood are what give Redwood 
it^ insulating power. 

Manufacturing plants on the Pa- 
cific Coast use Redwood as a substi- 
tute tor cork board for insulating. 

There are Mime splendid examples 
of Redwood's insulating power, as 
well as its remarkable longevity un- 
der the most severe service. in the old 
plant of the National Ice and Cold 
Storage Company, at Kentucky and 
Division streets, San Francisco. 
This -'lant was built in 1902 — 15 
years ago — and Redwood was used 
throughout. The system of brine 
piping is encased in Redwood boxes 
made of one-inch matched and sur- 
faced Redwood. Xearlv all of these 
insulation boxes are still in use. The 
temperature in the brine pipes is 6 

p-ees above zero, and they have 



gradually built up around the pipe, 
inside of the box, an incrustation of 
frost that completely fills the box. In 
spite of the fact that the temperature 
of the inside of these insulation 
boxes is 6 degrees above zero, and 
the temperature in the engine room 
of the plant is 80 degrees, there is no 
shrink, warp, swell, twist or check in 
these boxes, nor is there any gath- 
ering of frost on the outside of the 
box which would indicate free con- 
ductivity through the wood. 

Not only this plant, but most of 
the ice houses on the Pacific Coast 
use Redwood as lining for cold stor- 
age and ice rooms. In the plant above 
referred to there are ice storage 
rooms that have been in continuous 
use for 15 years, and where Red- 
wood has been incased with frost 
and ice for that period, and in spite 
of this severe service these rooms 
are thoroughly air-tight — the joints 
of the wood are tight. 

Roofs 

Redwood possesses a number of 
qualities that make it highly prefer- 
able for roofs, and particularly in 
factories where there is humiditx 
and condensation to contend with. It 
has been found particularly service- 
able in connection with the so-called 
"saw tooth'' type of roof. 

In many kinds of business such as 
cotton mills, paper mills, etc., where 
there is humidity or rising steam, 
there is trouble with condensation 
that drops back onto the products 
handled and creates a manufactur- 
ing loss. This is due to the fact that 
the roofing materials do not prop- 
erly insulate the sharp differences in 
temperature between the exterior 
and interior, and particularly where 
there is severe cold weather.

Redwood's natural resistance to

a> i' or alkalis, or the fumes of 
« hi mil als makes it preferable in

It i- light in weight and sufficiently 
strong under proper design. 

Redwood also possesses the neces- 
sarj attribute of holding its shape — 

when wet it does not swell and. when 

again dried, does not shrink percep- 
tibly. Redwood is not sensitive to se- 
vere changes of temperature or at- 
mospheric conditions which set up 



counteracting strains in wood. It can 
be depended upon to hold its shape 
when one side is subjected to freez- 
ing and the other to heat or humidity. 
Redwood is a thoroughly satis fac- 
tor) surface to paint. Its porosity af- 
fords a firm grip for the paint and 
makes it possible to get a thorough 
coverage. As Redwood, when thor- 
oughly dry, is subject to a minimum 
of movement in the wood itself un- 
der varying conditions of heat or 
moisture, there is a minimum ten- 
dency to check the paint film from 
^uch cause.

REDWOOD 



It is not neces- 
sary to subject 
Redwood to artifi- 

ial preservatives 
to give it durabili- 
ty — it possesses a 
natural durability 
that r e s i s t s rot 
both in contact with 
water, moisture or 
humidity, or sub- 
jected to conditions 
of heat or dryness, 
or severe alternat- 
ing dry and moist 

■ editions. Red- 
wood can be denied 
ventilation by seal- 
ing in metal, and 
under condition-- of 
this kind it has a 

high resistance to 
dry rot ; this same 
resistance to dry rot 
1- present even it the 
wood is not denied 
air. 

In Redwood, as in 
other woods, the 
heart stock will last 
longer than the sap. 
There is a sharp distinction between 
heart and sap in Redwood, as the 
natural color of the heartwood is a 
soft reddish-brown, while the sap- 
wood is white. Redwood sapwood, 
however, is a- durable as any other 
soft wood when painted.

Greenhouses 

Xur>t.rymen on the Pacific Coast 
have for years recognized the supe- 
rior service of Redwood for green- 
house purposes, and a number of 
uilders of greenhouses and green- 
house appurtenances in the East are

Redwood's remarkable durability 
in contact with moist soil, and the 
fact that it is unaffected by sudden 
changes in temperature or atmo- 
spheric conditions, make it highly 
preferable for sash bars and mun- 
tins. (ilass laid on Redwood green- 
house moulding does not become 
loose, rattle, and shatter because of 
decay in the moulding. 

Redwood makes a 'stay -tight 
joint, and therefore a leak - proof 
glass roof. Redwood does not swell 
perceptibly when wet, nor shrink and 
twist when again dried.

Redwood does not have to 
be treated to give it durability 
in contact with the ground; 
neither does it swell nor twist 
out of shape because the inside 
of the propagating box is in 
contact with wet ground and 
the exterior is dry. 

It resists attack by insects, and 

does not develop fungus growths. 

The use of Redwood about the 

reenhouse insures a maximum ser-

to work and the most satisfactory 

material to handle. 

Redwood in the greenhouse cuts 
the repair bill to a minimum.

president of the King Construction 
Company, North Tonawanda, N. Y.,

Gentlemen: We note by the little 
circular which you enclosed with your 
letter of February 13th that you show 
a couple of greenhouses which we 
built at Newton Falls, Ohio, these 
houses having been built throughout 
by our company of California Red- 
wood, 

Perhaps you would be interested in 
knowing why we use Redwood for 
greenhouse work. 

We have tried various kinds of 
woods that we thought might be suit- 
able for greenhouse work for the past 
20 years, and we have found Redwood

Brooders and Incubators 

Manufacturers using Redwood for 
incubators and brooders are enthusi- 
astic over its perfect adaptability. 

An incubator, because of the dif- 
ference in tempt ratine between the 
interior and the exterior, requires a 
wood that holds a tight joint, is un- 
affected by differences in tempera- 
ture, or alternating wet and dry at- 
mospheric conditions. 

;ht joints keep out drafts and 
give a higher working efficiency to 

the incubator. 

Redwo- ><Ts insulating ]>< >\\ er. its 
light weight, the ease in working, it^ 

resistance to rot a 1 tire, as well as 
its splendid surface to take and hold 
paint, are additional fax orahle fac- 
tors. 

The following letter from the pres- 
ident of the Petaluma Incubator 
Company sei^ forth the experience of 
one of the largest manufacturers of 

incubators and brooders in the coun- 
try : 

Petaluma, Cal., Sept. 30. 1916. 

Edwin K Myers, Sec. Manager, 

California R< dwood Association, 
San Francisco. 

E)car Sir: Before coming to Cali- 
fornia the writer used pine and other 



woods grown in Canada, but on com- 
ing to California Redwood was the 
most convenient to secure, and it 
proved to be a very happy result, for 
the Redwood used in these goods 
never shrinks or swells, and hence 
when we make good close joints to 
begin with, it remains so. Incubators 
made by us nearly forty years ago 
are still in use and, so far as the joints 
are concerned, they are as close now 
a^ when the machines were first con- 
structed. 

In our experience there is no wood 
which has come within our range that 
can equal or approach California Red- 

wood for making incubators and 
brooders, and 50 thoroughly were we 
convinced of that, more than thirt\ 
five years ago, that in all the time since 
we have not used other lumber. 

We have found that in shipping our 
nds to the Philippine Islands, Aus- 
tralia, India, South Africa, South 
American countries, such as Argen- 
tine, Uruguay. Brazil, Peru, and Chile, 
that the Redwood stands the ravages 
of the insects, such as the great white 
ant. These insects, which seem to en- 
joy making a breakfast of other kinds 
of wood, will not touch the Redwood. 

In addition we have shipped to al- 
most every place on the globe. Our 
incubators are used in Jerusalem, in 
Cairo. Egypt, in many of the islands 
f the Pacific and Atlantic oceans, and 
in the countries south of us, such as 
Mexico, Guatemala, Nicaragua, and 
even in the Canal Zone at the Isth- 
mus. In some of the latter mentioned 
■linns we regard the climatic con- 
ditions as trying on any kind of wood. 
There is no complaint, however, with 
Redwood. 

Respectfully, 

Petaluma [ni ubator Company, 

L. C. Byce, President

Ice Cream Cabinets 

Redwood is extensively used for the 
manufacture of ice-cream cabinets. 
It hah been found by actual experi- 
ence to be suited for this service. 

Experience is the most satisfactory 

demonstrator. Read what The (

Gentlemen: In answer to yours of

Redwood in be a better none iduc- 
tor of beat and cold than any other 

\\ 'd we could i^et, and, being light, 

it was less cumbersome to build our 

cabin from, as they have to be tak- 
en in every fall and put out every 
spring for service,

boards we have no glue joints; con- 
stant moisture and sometimes freez- 
ing would part these joints.

Redwood doe-- not warp if properly 
soned before it is used. 

Cabinets we built 15 years ago of 
Redwood, with sides 25J/2" wide, all 
in one piece, come in for repairs in 
perfect shape, and can be redressed 
and finished to look almost like new. 

We shall probably never use any 
other wood for the building of Nel- 
son cabinets. . . . 

Fifteen years ago we built 10 cab- 
inets and sold them for $100. This 
year our sales will amount to some- 
thing over $100,000. Fifteen years ago 
it was a new proposition to the ice- 
cream world. A great many thought 
it an unnecessary expense, but have 
since found it a very necessary ad- 



junct. It is growing even year and 
we never havt .1 complaint from our 
customers. 

Yours very truly,

Boxes and Chests 

Redwood is excellent material for a 
high grade clear box as a container 
for bulky goods of light weight, such 
as shirt waists, cereals, wearing ap- 
parel, etc. 

A number of candy shops on the 
Pacific Coast are using with great 
success a small Redwood box as a 
shipping container for candy. 

These boxes are made of clear, 
dry Redwood, and are labeled as 
"wood from the k big trees' of Cali- 
fornia/' This gives the box a senti- 
mental value, and, as the box is neat- 
ly made, it usually finds a permanent 

place in the recipient's home for some 

other purpose. 

A manufacturer of boxes in the 
east recently arranged for a large 
amount of Redwood to be used for 
shirt waist boxes. The Redwood is 
cut thin, and the completed box is 
covered with matting glued to the 
wood. These boxes are to be used to 
ship shirt waists to tropical countries. 

Redwood chests are splendid for 
storing wearing apparel, valuables, 
etc. The ease with which the surface 
can be worked for decorative pur- 
poses makes it possible to produce a 
handsome and extremely durable 
chest that is a rapid seller. Manx 
Redwood chests are decorated with a 
sandblast figure. They can also be 
-tained to any color desired. 

m 

Manufacturers of office filing 
equipment use Redwood for hit- 
transfer cases because of its light 
weight and ability to hold a tight 
glued joint.

Storage Battery Purposes 

I f Nature had determined to grow a 
wood -especially suitable for storage 

battery uses, and particularly as sep- 
arators, she could not have improved 
upon Redwood. 

Redwood meets these require- 
ments satisfactorily. In fact Red- 
wood is so perfectly adaptable for 
battery purposes that the Electric 
Storage I lattery Company, of Phil- 
adelphia, Pa., has taken out letter- 
patent on the use of Redwood in 
their batteries, and in which patent 
the following statement is made : 

"The quali common to these- woods that 
adapts tli< m to stor. hattery separators

wet and consequently, when again driel, of 
not shrinking, v rping or twisting to an

was granted December 26, 191 1. 

Organs 

The highest possible evidence of 

Redwood's "staying-put" quality can 
be found in the fact that it has been 
used for years with absolute satis- 
faction as a material from which pipe 
organs are made. 

The organ is a delicate instrument, 
as the slightest leak would he disas- 
trous to the tone. 

The organ manufacturer cannot 
u>e a wood that varies in the slight- 
est, either through change in temper- 
ature or atmospheric conditions, or a 
Wi d that contains pitch or gumm\ 
substances to deaden the resonance 
of the wood or leak into valves. 

The following letter from the sec- 
retary of the California I >rgan ( om- 

pany of Los Angeles indicates the 

high confidence that company has in 
Redwood :

absolute assurance that 
our work is going to

pletion. For instance, 
a Redwood pipe does 
not expand or contract 
under a great variety 
of climatic and atmos- 
pheric conditions. This

as the cubical area < E

pitch, mid should a 
pipe move from its 
fixed position an in- 
strument would mo\ 
slightly out of pitch.

instrument \\ i find 
Redwood to be of ex- 
ceptional value. There 

re hundreds of small 
felt and leather valves, 
and should the wood 
exude pitch these tiny 
parts would stick and 
refuse to work. It is 

Iso an advantage in 
client work as it is 
essential that these 
chests should be air- 
tight, and the possi- 
bility of checking is 
minimized in the use 
of properly dried 
Redwood.

Los Angeles, Cal., Sept. 12, 1916. 
Californi \ Redwood Assn.. 

San Francisco, California. 

Gentlemen: In regard to Redwood 
in the manufacture of pipe organs, 
there are, of course, several reasons 
for our using the same. 

I he woods usually used in this type 
of construction, or those which have 
been u^ed in the past are white cedar 
and sugar pine. 

A governnient report shows the rel- 
ative value of Redwood, white cedar 
and sugar pine in the order men- 
tioned, concerning the lasting quali- 
ties, absence of swelling and shrink- 
age, and the absence of pitch. 

The principal advantage to us i- the 



swell boxes and the 
larger pipes is the fact that Redwood 
is obtainable in any dimensions, ex- 
traordinary width being demanded at

There are two other important rea- 
sons. In the matter of cost, as com- 
pared with the woods used by other 
manufacturers in this line, the initial 
price as compared to su r pine is ap- 
proximately 50 per cent ; as compared 
with white cedar, Redwood is slightly 
lower in price and is vastly superior 
to it. It also has the advantage of be- 
ing light, consequently shipping rates 
are greatly reduced. 

In closing we beg to advise that we

Redwood is one of the four woods 
specified by the Fire Underwriters 
Laboratories as a material from 
which fire-door cores should be built. 

Of these four woods Redwood is 
the first preferred, for these reasons: 

1. Natural resistance to fire be- 
cause of slow ignition and 
slow burning. 

2. Absence of pitch, resin, or 
other inflammable elements.

Gentlemen: In reph to vour letter 
of August 15th. 

There has been much discussion on 
the relative merits of various soft 
woods to be used in the construction 
■ »f fire doors. 

In my experience I find that Red- 
wood is the best wood in all cases, it 
having, you might say, no pitch in it, 
which makes it almost non-burnable. 
Also, it does not dry-rot when en- 
closed by metal and denied ventila- 
tion. 

Most woods I have noticed that are 
incased in metal will sooner or later 
dry-rot. and I ha\c noticed a number 
of doors after having been enclosed 
for seven or eight years were reduced 
to a scrap or junk through dry-rot. 

We are the largest manufacturers 
of fire doors on the coast, and we have 
never had one complaint about our 
material going bad. In fact, in the 
course of a change in one of the Pa- 
cific Telephone Buildings in San Fran-

f the metal doors in two that we 
manufactured; the door in mention 
having been in place for about eight 
years, ami he, the engineer, returned 
a part of it to US and a letter stating 
that the door was in just a- gnnd a 
condition as the dav \w manufac- 

lured it. 

Also, another thing that T noticed 
on the Redwood door- is that after 
they had 1 n subjected to a fire they 
are not burnt up. I could cite a num- 
ber of incident-, but 1 remember one 
in particular in which I went to ex- 
amine the doors after a lire. I found 
that the door next to the fire had been 
charred possibly one-quarter of an 
inch dec]). The fire did not get in any 

further; in fact, it stopped, and a< 1 

said, this is due to the fact that there 
i- no pitch in the wood to help it burn. 

\tter the hre at the Times Mirror 
Company's plant (the Los Angeles 
Daily Times explosion), I noticed on 

ihe building across the alley there was 
a shutter protecting a window open- 
ing. Considering the great heat from 
the explosion and fire the shutter had 
fulfilled its duty much more so than 
n> other protection used on the ad- 
joining window. In fact, some of them 
had hollow metal windows and frames 
and they had gone absolutely to pieces, 
but this Redwood shutter kept the tire 
out of this particular opening; and 
without doubt in my mind if they had 

been used on the adjoining openings 
they would have saved that building. 

In conclusion, you can see where I 
stand regarding the use of Redwood. 
We will not use anything else be- 
cause I deem it that our customers 

r< entitled to. the best and it i- up to 

IS to see that they get it. 

Yours very truly, 
California Fire-proof Door Co,

Fire Walls 

Redwoods slow ignition, slow burn- 
ing and the ease with which tire is 
extinguished have made it the recog- 
nized material for fire doors. 

Experience on the Pacific Coast 
has demonstrated that a solid Red- 
wood fire wall will perform its func- 
tion satisfaet* >rily. 

Building ordinance No. 399, of the 
city of Eureka, California, is typical 
of the permitted use of Redwood for 
fire- wall purpose-, and reads as fol- 
lows : 

Sec. j. The exterior walls anil all party 
walls of the buildings luded within the 

district above described, shall be con- 
structs! of concrete or 1 k, natural or 
artificial stone, or iron or a combination of 
any or all of the above described materials, 
of Redwood as pro. ill by this ordi- 
nance. 

Sec. 3. The height of all wooden build- 
ings hereafter constructed within the fire 
limits shall be limited to 50 feet, from the 
sidewalk grade to top of fire wall or peak 
of roof. 

Sec. 4. All wooden buildings hereafter 
erected within the fire limits of the city of 
Eureka, except those built for. and used 
exclusively as dwelling houses, outhouses, 
and private stables, shall be constructed 
with solid wall-, the same to be not less 
than four inches thick in all one and two 
story buildings, and in all three or more 
story buildings, the tw<< upper stories -hall 
be constructed with soli 1 walls of like 
thickness, and the lower story or stories 
shall be constructed with solid walls not 
less than six inches thick. The above thick- 
ness of walls to be exclusive of pla . 
weather boarding or rustic. 

All frame buildings with Studded walls 
or where the walls are not solid, shall have 
their outer walls covered with rustic or 
weather boarding, and the walls of such 
frame building- shall not come in contact 
with, or be within twelve inches of, the 
walls of any other building. Such inter- 
vening space shall not be enclosed higher 
than six feet from the ground.

Electrical Specialty V*/or\ 

The absence of pitch or gummy sub- 
stances, its straight even grain, its 
non-conductiviu . and its resistance 
to fire are the features that make 
Redwood preferable for electrical 
mouldings and specialty work. 

Screens 

As Redwood is light, easy to work 
and makes a satisfactory and perma- 
nent joint it is in demand for the 
manufacture of screens. 

This applies to the fly screen as 
well as special work such as screen - 

for moving pictures, portable screens 

for the home. etc. 

The absence of pitch or raised 
grain and the natural surface of the 
wood lend it admirably to decorative 

- 

pur]",- . either by carving, painting. 
staining, gluing or fastening mould- 
ing 

Redwood screens do not shrink or 
warp out of joint, and they have a 

high resistance to rot, whether ex- 
posed to the weather or to conditions 
that would promote dry rot. 

Fireless Coo\ers 

The non-conductivity of Redwood, 
together with its ability to make a 

tight joint, and hold the joint regard- 
less of the difference in temperature 
betw *n the interior and the exterior 
of the tireless cooker box, are qual- 
ities that give Redwood a decided 
] "reference for this use. 

It- light weight, ea-y working, per- 
feet surface to paint, and its dur- 
ability are also favorable factors. 

Manufacturers of fireless cooker 
can buy Redwood to advantage be- 
cause it can be furnished cut to tin 
sizes required at a material saving 
ompared with buying regular sta\ 
lengths. 



Sta\es and Fence Posts 

Because of its wonderful durability 
in contact with the ground there is no 
wood like Redwood for stakes and 
fence posts. It is used almost exclu- 
-ively in the vineyards and ranches 
of California. 

Enormous quantities of Redwood 
stakes are set annually in the vine- 
yards and hop fields of California. 
These stakes are split and come in 
two sizes, 2x2 in. and 6 ft. and 2 x 
2 in. — 8 ft. 

Redwood split posts come stand- 
ard 4 inches by 5 inches and ~ feet 
long. Sawn posts come in lengths of 
6 feet, 7 feet and 8 feet, and 3 inche 
by 4 inches, 4 inches by 4 inches and 
4 inches by 6 inches. 

The wonderful durability of Red- 
wood in contact with the ground was 
recognized by the Lincoln Highway 
< ommissioners of the west when they 
-elected Redwood for marking post- 
for that part of the roadway be- 
tween Salt Lake City and San Fran- 
cisco, a distance of 1000 miles. Each 
mile of this distance is to be marked 
with a Redwood post. 

The Highway Commission had be- 
fore it a proposition to mark this 
highway with boiler tubes set in a 
concrete base, but it was found thai 
in addition to the expensive setting- 
up cost the boiler tubes could not b« 
guaranteed to stand as long as the 
Redwood post, which, without any 
attention, is good for 25 years and 

upward. 

The overland traveler in an auto- 
mobile is therefore welcomed to Cal- 
ifornia by a thousand mih s of Red- 
wood posts that guide him to the 
land of "big trees," golden ri\<r- 
and the most worn rful lumber in 
the world — Redwood.

Bee Hives 

Re dwood is without question the best 
adapted wood tor bee hives. 

Its light weight, easy working and 
its ability to hold tight joints regard- 
less of alternating conditions in the 
atmosphere, as well as its durability 
without protection of preservatives, 
make it a material which, when used 
in the bee hive, can be depended upon 
to last a life-time. 

Redwood is odorless and tasteless 
and has no deleterious effect on the 
honey. 

Ree hive stock in Redwood is ob- 
tainable in cut lengths according to 
specifications desired. 

Fruit Trays 

In the great fruit-growing sections 
if ilifornia the Redwood tray is 

used for sun-drying fruits. 



These trays are made of Redwood. 
They are set on the ground with the 
fruit in them, and are thus exposed, 
during the curing process, to the hot 
rays of the sun. 

Setting on the moist ground they 
are naturally subjected to curling or 
warping on account of the conflict- 
ing strain set up in the fiber of the 
wood by the v arying degrees of dry- 
ness on both sides — and Redwood 
stands thi> -.train without sacrifice of 
shape. 

In addition. Redwood is light and 
easy to handle. 

Cigar Boxes 

Redwood is rapidly finding favor 
among manufacturers of cigar boxes 
as a suitable wood for this purpose. 

In strength and color it compares 
favorably with cedar, and is odorless.

REDWOOD 



Redwood possesses the remarkable 
quality of "staying put" when prop- 
erly dried, regardless of atmospheric 
or climatic changes or conditions, and 
holds labels perfectly. 

Cigar box stock should be vertical 
grain, thoroughly dry and clear. It is 
furnished either in flitches, or cut to 
fecial *-ize for immediate use. 

Bill-Board Moulding 

Redwood is recognized by the bill 
posters of the United States as supe- 
rior for bill -board moulding. 

Bill-boards are exposed to rough 
weather. and the essentials, therefore, 
are a lumber of great durability un- 
der varying climatic conditions, a- 
well a- a surface that takes and holds 
paint perfectly. 

Redwood meets all these require- 
ments. 

Redwood is the most durable lum- 
ber for bill -board purposes. It is light 
in weight and easy to work. It does 
not rot because of dampness between 
the moulding and the bill-board. 

For po>ts and backing Redwood 
will last longer than the sign-board 

itself. 

I\ cd wood bill-boards require less 
Up-keep attention and cost. 

Lead Pencils 

I he rapidly diminishing supply of 

edar for lead pencil stock is causing 

the pencil manufacturers to look for 

other suitable wood-, and they find 

Redwood adaptable. 

It not onlv closely resembles cedar 
in color, hut a vertical grain Red- 
wood pencil can be sharpened as 
readily as a cedar pencil. 

Redwood pencil stock, to be entire- 
1\ satisfactory, must be carefully se- 

lected a-- to grain, softness and the 
number of annular rings. 



It is light in weight, can be thor- 
oughly dried, and is a splendid wood 
to glue. 

Pencil manufacturers in this coun- 
try have been using Redwood for 
many years, and large quantities are 
shipped abroad for this purpose. 



Redwood Burl 

Hurl is not lumber — it is a lump 
growth on the exterior of the tree, 
usually covering a wound. 

Large quantities of burl are used 
for novelties, such as pipe trays, 
plates, bowls, etc., and these in many 
instances have left the impression, 
particularly in the east, that burl is 
Redwood. 

Burl is gnarly, plentifully spotted 
with small knots, hard, and takes a 
high polish in imitation of mahog- 
any. 

Burl does not grow on all trees, 
and, as a result, it is very scarce. This 
scarcity, together with the big de- 
mand from novelty manufacturer^ 
keeps it at a big premium in the mar- 
ket. 

Camera Stoc\ 

The light weight of Redwood, its 
ability to make and hold a tight joint. 
and the absence of shrink, swell, or 
warp, regardless of atmospheric or 

climatic conditions, combined with il 
«asy working quality, make it espe- 
cially adaptable for camera stork. 

Redwood also lends itself splendid- 
ly to firm gluing of camera covering. 

Redwood camera boxes can alwa\ 
be depended upon to remain lighi 

proof, and thus insure perfe* t ser- 
vice by the camera.

. Toys 

The manufacturers of tors are turn- 
ig to Redwood because it not only 
affords a sentimental factor that is a 
powerful influence in its sale, by rea- 
son of the fact that it is wood from 
the "big trees" of California, but 
also because it is splendidly adapted 
to such purpose. 

It has light weight, smooth even 
grain, will not swell or curl, is easy 
rid profitable to work and has a 
''right, warm color. 

Redwood toys are not only a diver- 
sion, but an education to the child by 
reason of the fact that they awaken 

mm 

n interest in the "big trees" — a sub- 
ject that is familiar to every school 
child in the nation. 

Par\ Equipment 

For benches, gutters, and curbing, 
plant stakes, planking, etc., because 
of its natural durabilitv in contact 
with the ground, Redwood is the 
wood to use. 



It is universally used in the parks 
in the western section of the count r\ . 
where Redwood is so well known. 

Enormous quantities of Redwood 
were used for this purpose in both 
the Panama-Pacific International Ex- 
position in San Francisco in 191 5, 
and the Panama-California Exposi- 
tion in San Diego in 1915-1916. 

Redwood's adaptability to paint 
makes it particularly preferable for 
park benches and settees, pergolas, 
porches, etc.. where the building ma- 
terial must not only have durability 
but a natural resistance to the 
weather. 

Because it does not warp and swell 
Redwood is preferred for grandstand 
benches and bleacher seats at base- 
ball parks and athletic grounds. 

Redwood park equipment insures 
long life at a minimum cost. 

Ship Interiors 

Redwood has been used for many 
years as interior finish and cabin par-

titions on passenger ships, both in 
this country and in England, where 
millions of feet of Redwood "bulk- 
heading" have been installed on fast 

Atlantic liners. 

It is superior for ship interiors for 

these reasons — 

1. Its resistance to fire, and ease 
in extinguishing when afire. 

2. Lack of shrink, warp, or swell 
due to changes in tempera- 
ture or climate. 

3. Redwood always looks well — 
it "stays put." 

4. Resistance to wet or dry rot. 

5. Its extremely light weight 
makes it preferred for super- 
structure in boat-building, 
where the center of gravity is 
an important factor. 

6. It is a perfect surface to take 
and hold paint, stain, or 
enamel. 

7. It has splendid adaptability 
for decorative effect, because 
of its smooth surface and 
straight grain. Wonderful 
panel effects can be achieved 
in cabins 1a the use of stain 
or sandblast. 

Pattern Stoc\ 

Manufacturing institutions on the 
Pacific coast have used Redwood for 
pattern stock for many years. 

Thoroughly dry Redwood can be 
depended upon to make a satisfac- 
tory joint ; it i^ easy and profitable to 
work, and is not affected by variation 
in atmospheric conditions from 
moisture to dryness. It can be de- 

- 

pended u n to hold its shape. 

The pattern makers in the east are 
turning to Redwood because of this 
last characteristic, and I :ause it is 
thorough h satisfactory to work. 

Pattern lumber should be selected 



for soft even grain, and it must be 
thoroughly dry before using. In ad- 
dition to the clear grade many pat- 
tern makers use a selected high grade 
of "shop" lumber which costs consid- 
erably less, and in no way affects the 
value of the finished pattern. 

'Veneer Core 

The porosity of Redwood makes it 
absolutely dependable as veneer core. 

The holding quality of a core de- 
pends upon its absorbing power or 
anchorage for glue. Kiln-dried Red- 
wood is a perfect gluing surface. 

In addition to Redwood's light 
weight it does not deteriorate by dry 
rot. even when denied ventilation. It 
is virtually immune from the attack 
of insects. 

Thoroughly seasoned Redwood 
does not shrink, swell or warp, and 
the core will always hold its proper 
shape. A Redwood core is not af- 
fected by sudden changes in temper- 
ature or climatic conditions, and, 
therefore, holds the veneer from 
moving from the same causes. 

Manufacturers using veneer in 
large quantities have thoroughly in- 
vestigated Redwood as a core, and 
find it meets all requirements, and 
particularly for such fine work as 
pianos, desks, furniture, hardwood 
veneer doors, panels, and so forth. 

Veneer core stock is furnished in 
Redwood in small pieces cut to size, 
rough or built up stock. 

A manufacturer of canoes in the 
east is using Redwood cores be- 
tween birch veener for canoes. After 
considerable experimenting he finds 
that Redwood is perfectly adaptable 
to this use for the reason that tin 
porosity of the wood affords a per- 
1 t surface to glue, and also con- 
tributes to lightness.
